No customer service at all no manners

I have never met any one as rude as there staff they rude to a disabled lady hoe just went through the worse kind of trauma ever then they phone the family members (me the daughter) and scream and shout at me for no reason when i ask her why she is rude she wants to blame me for her rude ness and funny part is i have a witness to how polite i was to her and here she is shouting at me rudely when i asked to speak to the super visor and then im told she is the super visor and the best part is i was kind to her and here she is screaming and shouting at me. After my mother informed them about the hole trauma she still gets treated so bad that they have her in tears and devastated even moor where is the customer service where is the manners to speaking to a client my mother was traumatized enough as it is and here they make moor damage . We will never fly with mango again and ill make sure to spread the word on how they treat there clients so that no one i know will fly with them again.
